`main`: Cannot run / install using Python 3.13

The program cannot install its requirements under Python 3.13 on Linux, rendering it unusable on Bazzite OS

The error upon running pip3 install -r dependencies/requirements.txt is as follows:

bazzite@bazzite:/run/media/bazzite/5658C8E658C8C5C9/Users/wolfy/Git/TournamentStreamHelper$ pip install -r dependencies/requirements.txt 
Defaulting to user installation because normal site-packages is not writeable

ERROR: Could not find a version that satisfies the requirement pyside6==6.7.0 (from versions: 6.8.0.2, 6.8.1)
ERROR: No matching distribution found for pyside6==6.7.0

Start with dependencies/requirements.txt and reproduce the reported pip3 install -r dependencies/requirements.txt command under Python 3.13. Inspect the pyside6==6.7.0 constraint and determine a dependency configuration that installs successfully on the reported platform; done means the requirements install completes without the shown version error.
